Open-Faced Steak, Pear, and Gorgonzola Sandwiches

Subtly sweet, crunchy pears are an excellent addition to any sandwich, especially when counterbalanced by a creamy, strong-flavored cheese as here. The seared tender flank steak turns the sandwich into a meal. Serve open-faced on flatbread or pita with a knife and fork, or try it on lightly toasted focaccia as a closed sandwich.
